My Goodman GMPN080 furnace has been acting strangely for several years now.
After a concerted effort, I have determined that the stack over temp switch
is opening at 140 degrees F, and not closing until it gets down to about
110 degrees F. This causes the gas valve to shut off. The controller
tries three times to relight it, then shuts everything off for an hour,
with a single LED flash code on the controller card.
My question is: is this switch malfunctioning, or is 140F an unusually high
temperature?
Thanks,

I have never heard of a "stack over
temp switch", but then again, I'm new at this...20 years....

Wait until you've had MY years of experience, Junior.
You still won't have heard of it, but you'll have learned not
to give a shit :-)
